## skchem.standardizers.chemaxon
Module wrapping ChemAxon Standardizer. Must have standardizer installed and license activated.
skchem.standardizers.chemaxon.
ChemAxonStandardizer
(config_path=None, keep_failed=False, **kwargs)[source]¶Bases: skchem.base.CLIWrapper
, skchem.base.BatchTransformer
, skchem.base.Transformer
, skchem.filters.base.TransformFilter
ChemAxon Standardizer Wrapper.
Parameters: | config_path (str) – The path of the config_file. If None, use the default one. |
---|
Notes
ChemAxon Standardizer must be installed and accessible as standardize from the shell launching the program.
Warning
Must use a unique index (see #31).
